Hemangiomas of the tongue and the oral cavity in a myotonic dystrophy type 1 patient
<p>Myotonic dystrophy type 1 (DM1) is an autosomal dominant disease caused by a cytosine, guanine, thymine (CTG) trinucleotide repeat expansion in the non-coding region of dystrophia myotonica protein kinase gene, causing a multisystem involvement. To date, few studies have been performed to evaluate skin features in DM1 patients, but none reported on the possible association between the disease and tongue hemangiomas. We report a case of a 63-year-old woman affected by DM1 and presenting, at the intraoral examination, several swelling and buish lesions occurring on buccal and palatal mucosa, and in the anterior two-thirds and margins of the tongue. Multiple tongue hemangiomas in DM1 patient. Color Doppler ultrasound revealed hypoechoic lesions with intermittent color picking suggestive of vascular lesion. Surgical excision was performed under general anesthesia. Histopathological examination was compatible with the diagnosis of cavernous hemangiomas. At 6 months follow-up, a part from the cosmetic deformity, patient's hemangiomas did not bleed, but caused functional problems with speaking, mastication, and deglutition, in addition to the same symptoms induced by DM1. This case may add new details to better characterize the DM1 phenotype, suggesting that even tongue hemangiomas may be part of the DM1 multisystem involvement.</p>

Spectral Engineering of Cavity-Protected Polaritons in an Atomic Ensemble with Controlled Disorder
<p>The paradigm of N quantum emitters coupled to a single cavity mode appears in many situations ranging from quantum technologies to polaritonic chemistry. The ideal case of identical emitters is elegantly modeled in terms of symmetric states, and understood in terms of polaritons. In the practically relevant case of an inhomogeneous frequency distribution, this simple picture breaks down and new and surprising features appear. Here we leverage the high degree of control in a strongly coupled cold atom system, where for the first time the ratio between coupling strength and frequency inhomogeneities can be tuned. We directly observe the transition from a disordered regime to a polaritonic one with only two resonances. The latter are much narrower than the frequency distribution, as predicted in the context of ''cavity protection''. We find that the concentration of the photonic weight of the coupled light-matter states is a key parameter for this transition, and demonstrate that a simple parameter based on statistics of transmission count spectra provides a robust experimental proxy for this theoretical quantity. Moreover, we realize a dynamically modulated Tavis-Cumming model to produce a comb of narrow polariton resonances protected from the disorder, with potential applications to quantum networks.</p>

Data of Forced-response characterization of PBF-LB/AlSi10Mg particle dampers with thin and flat cavities
<p>Powder Bed Fusion (PBF) enables the production of complex geometries which offer the opportunity to manufacture lightweight, stiffness-optimised or integrally designed components. Although these properties are usually advantageous for the performance in many applications, they pose disadvantages under vibration as they lead to low damped components. These are prone to high vibration amplitudes which result in higher sound radiation and a reduced lifetime. Particle damping can counteract these disadvantages. By including cavities during the design process, unmelted powder remains inside the component after its production. This powder dissipates energy under vibration by inelastic impacts and friction in particle-–particle or particle-–wall-interactions, increasing the damping characteristics of the component. In this work, additively manufactured AlSi10Mg specimens with cavities are investigated with respect to their damping characteristics by experimental modal analysis. The focus of the investigation is on thin and flat cavities that can be easily integrated into components without adapting the external geometry. The damping characteristics in dependence on excitation amplitude and mode are quantified. The extent to which settling effects of the powder during shaking influence the damping is analysed. The vibration of the specimens is forced by an electrodynamic shaker and their response is measured contactlessly via Scanning Laser Doppler Vibrometry (SLDV). A damping effect of up to 564% depending on the mode, excitation amplitude and specimen can be achieved. In addition, a significant settling effect of the powder which hampers the damping effect is identified by CT scans and modal analysis.<br> The data of the CT scans as well as the data of the modal analysis is uploaded here. </p>
Data from: Fast visual adaptation to dim light in a cavity-nesting bird
<p class="MsoNormal"><span>Many birds move fast into dark nest cavities forcing the visual system to adapt to low light intensities. Their visual system takes between 15 and 60 minutes for complete dark adaptation, but little is known about the visual performance of birds during the first seconds in low light intensities. </span></p> <p class="MsoNormal"><span>In a forced two-choice behavioural experiment we studied how well budgerigars can discriminate stimuli of different luminance directly after entering a darker environment. The birds made their choices within about one second and did not wait to adapt their visual system to the low light intensities. When moving from a bright facility into an environment with 0.5 log unit lower illuminance, the budgerigars detected targets with a luminance of 0.825 cd/m<sup>2</sup> on a black background. When moving into an environment with 1.7 or 3.5 log units lower illuminance, they detected targets with luminances between 0.106 and 0.136 cd/m<sup>2</sup>. In tests with two simultaneously displayed targets, the birds discriminated similar luminance differences between the targets (Weber fraction of 0.41-0.54) in all light levels. Our results support the notion that partial adaptation of bird eyes to the lower illumination occurring within one second allows them to safely detect and feed their chicks. </span></p>

Phylogeography of cavity-nesting honeybees (Apis)
<p>We examine phylogenetic relationships among species and populations of Asian cavity-nesting honeybees, emphasizing detection of potential unrecognized species in the geographically widespread <em>Apis cerana</em> Fabricius (Hymenoptera, Apidae). We carried out a phylogenetic analysis of genome-wide single nucleotide polymorphisms (SNPs) using BEASTv1.8.4 and IQ-TREE 2. Our samples cover the largest geographic area and number of populations of Asian cavity-nesting honeybees sampled to date. Nodes in the tree were calibrated using the mid-Miocene giant honeybee <em>Apis lithohermaea</em> Engel. We used STRUCTURE, Bayes Factor Delimitation, and discriminant analysis of principal components to infer probable species among populations of cavity-nesting honeybees currently recognized as <em>Apis cerana</em>. Our results support four species within <em>A. cerana</em>: the yellow "plains" honeybee of India and Sri Lanka; the lineage inhabiting the oceanic Philippine islands; the Sundaland lineage found in Indonesia, Malaysia and parts of southeast Asia; and a Mainland lineage, which we provisionally consider <em>A. cerana</em> in a narrow sense.</p>

Data for: Cavity-breeding birds create specific microhabitats for diverse arthropod communities in boreal forests
<p class="MsoNormal">The nests of secondary cavity-nesters located in tree cavities may form specific microhabitats of conservation importance due to their limited accessibility and availability. Species-specific nesting materials in nests of different secondary cavity-nesters may furthermore provide very different microhabitats for arthropods. The potential differences in arthropod communities inhabiting nests of different bird species in excavated cavities or nest boxes have, however, rarely been studied despite their relevance for conservation. Here we investigated the diversity and composition of arthropod communities in these different cavity types and bird species' nests in managed boreal forests. We identified morphologically and by DNA-metabarcoding arthropods in nest materials that were collected in and compared between i) woodpecker-size cavities from seven different combinations of cavity type (nest box or excavated cavity), tree species (aspen or pine) and accumulation history of nest materials (single-season cleaned or uncleaned nest boxes that accumulated nests of passerines or an owl species); and ii) nests of two different passerine species in small nest boxes. We identified 64 arthropod taxa in ten orders, from which Diptera, Coleoptera, Siphonaptera, and Lepidoptera were the most abundant. Shannon diversity index was similar among the cavity-nest-type combinations, but taxa richness was the highest in the owl nests. The arthropod communities (especially Histeridae beetles) deviated most from the other types of nests in owl and aspen cavity nests with more advanced decomposition of nest material (soil or wet environment-related taxa). The differences in arthropod communities between the different nest types point out the importance of the ecological chain "tree cavities – bird nests – arthropod communities".</p>
